I read a article about that exact situation a while back. This guy picked up a prostitute whom he thought was female. But in getting down to business, he discovered”she” was really male.
So you wonder if these transvestite prostitutes are attacked and killed not because of being dressed that way, but because they are pretending to be females.
I wonder if these transvestite prostitutes use their female attire as cover for their physical strength as men. When an unsuspecting John is in his most vulnerable position, using the advantage of their strength, they attempt to rob him of his money. The John reaches for his wallet in one pocket and his gun in the other. The transvestite over played his advantage.
